40 million... I knew there was a lot, but didn't realize that many. Another comment says closer to 5 million physical towers, still a lot.
A lot of these towers have GPS receivers for clock syncing as well, don't they?
Back in college I had a geology prof who was using GPS receivers planted in one spot to measure seismic / tectonic movements from one year to the next.
That was over 10 years ago, and I never looked into it much more, but seeing all those dots reminded me again.
I've wondered what kind of resolution they could model with data from the hundreds of cell towers in the area vs the handful of stations they maintained?
